What Coolors is
Coolors is a colour tool built for speed. Generate palettes, lock the colours you want to keep, keep generating around them, extract colours from an image and check contrast before handing work over.
It is about narrowing choices quickly rather than editing graphics.
What you can do with it
- Generate and compare colour combinations fast
- Lock colours while exploring the rest
- Extract palettes from reference images
- Check contrast for readability
Who it is for
- UI and graphic designers
- Brand and visual teams
- Product teams defining a palette
- Anyone improving colour workflow
What to watch out for
- It generates candidates; brand suitability still needs judgment
- Contrast checks should be verified against the actual accessibility standard you follow
- Palettes need testing in real interface contexts
- Not a graphic editing tool
